I'm using the E3200 and while the PPTP passthrough works fine, it disconnects after a few minutes(tested from 2 different Win7 machines). The RRAS server is a Win2k3 server. I found a link that adds a few startup commands, which I've recently added, but it doesn't seems to have helped.
I'm on the latest supported/recommended firmware I believe. When I go to the router database and type in my router(the E3200), there is a specific firmware for my router. Is there a different firmware I should be using?
